generate correlated qualitative data
Dear R experts:
I have following problem:
# myfunction
mfun1 <- function(x) {
if ( x == 2){
xv <- sample(c(2,1,0),100, replace = T, prob = c(0.6, 0.2, 0.2))
}
if ( x == 1){
xv <- sample(c(1,0),100, replace = T, prob = c(0.6, 0.4))
}
if ( x == 0) {
xv <- sample(c(0,0),100, replace = T, prob = c(0.5, 0.5))
}
return(xv)
}
# applying the function
x = mfun1(1)

correlated data
Hi!!
I am trying to generate data with specific correlation using corgen method from the ecodist package. It does not seem to generate the data properly. I am listing the code below. Secondly, when I put the code given below all in one file and source it, it is unable to complete the task. But when I execute it one at a time it is able to complete it. Can someone point out any mistake that I may

Generating uniformly distributed correlated data.
I wish to generate a vector of uniformly distributed data with a
defined correlation to another vector
The only function I have been able to find doing something similar is
corgen from the library ecodist.
The following code generates data with the desired correlation to the
vector x but the resulting vector y is normal and not uniform
distributed
library(ecodist)
x <- runif(10^5)

Puzzled on nlm
Dear R People:
Here is a function to minimized:
>mfun1
function(x,a) {
x[1] <- a[1]*x[2] + a[3] - a[2]*(a[1]-a[2])*a[3]
x[2] <- a[1]*x[1] - a[2]*a[3]
return(x)
}
Here is my first try:
>nlm(mfun1,c(1,1))
Error in f(x, ...) : Argument "a" is missing, with no default

easy-to-use tool to assist in the analysis of textual data. At the
present, it supports only plain text format data. All the information
is stored in SQLite database via the R package of RSQLite. The GUI is

nlm question
Dear R People:
I am trying to duplicate the example from Dennis and Schnabel's "Numerical
Methods for Unconstrained Optimization and Nonlinear Equations", which
starts on page 149.
My reason for doing so: to try to understand the "nlm" function.
Here is the function:

z <- matrix(0,nrow=2,ncol=1)
z[1,1] <- x[1]^2 + x[2]^2 -

partial mantel tests in ecodist with intential NA values.
I would like to perform partial mantel tests on only within group values, with "between group" values assigned to NA.
This is possible in package ncf partial.mantel.test, however this sues a different permutation to that used in ecodist.ecodist will not accept data with NA values, returning a "matrix is not square error.
is it possible to perform this test in ecodist?
many thanks

Simulate binary correlated data
Dear R experts,
I am trying to simulate correlated binary data and have stumbled upon the
following problem:
With the help of "binarySimCLF" or "mvpBinaryEp" I have been able to
simulate correlating binary vectors given certain mean values and a desired
correlation. My problem is that these procedures do not allow you to specify
the exact vector for which you want to generate

Generalized additive models: Plots for Qualitative Data
Hello,
My name is Dontrece Smith. I am creating figures for my GAMs. I change my
qualitative variables to 1 or 2 in my dataset, so I would be able to run my
GAMs. However, R will only display plots for my quantitative variables and
not my qualitative variables. Is there any way to fix this issue? I listed
some of my code below:

Qualitative Data??(String command)
I am using the read.table function to load an Excel data set into R.
It has a few variables with very long qualitative (free response
typically in sentences) response that I would like to keep, but would
like to limit the "length" of the response that R shows. Is there some
sort of string or column width command I can include in the read.table
function to limit the length of words used

Competing Risks Regression with qualitative predictor with more than 2 categories
Hello,
I have a question regarding competing risk regression using cmprsk package (function crr()). I am using R2.9.1. How can I do to assess the effect of qualitative predictor (gg) with more than two categories (a,b,c) categorie c is the reference category. See above results, gg is considered like a ordered predictor !
Thank you for your help

Qualitative factors
Hi,
I have some doubt about how qualitative factors are coded in R. For
instance, I consider a response y, a quantitative factor x and a qualitative
factor m at 3 levels, generated as follow :
y_c(6,4,2.3,5,3.5,4,1.,8.5,4.3,5.6,2.3,4.1,2.5,8.4,7.4)
x_c(3,1,3,1,2,1,4,5,1,3,4,2,5,4,3)
m_gl(3,5)
lm(y~x+m)
Coefficients:

qualitative response model
Hi, I want to know is there other functions in R to
estimate qualitative response model besides multinom()
in library nnet, if this is the only possibility, I
have a question about the application:
for example:
there is three transportation choice : car, bus ,
subway.
each alternative has own characteristic variables,
I want to apply conditional logit model to analysis
